Abstract (en)
A battery (200) includes at least an electrode group (100) including a positive electrode (10), a separator (30), a negative electrode (20), and a protection layer (410). The separator (30) is interposed between the positive electrode (10) and the negative electrode (20). The positive electrode (10) includes a positive electrode current collector (11), a positive electrode mixture layer (12), and a positive electrode tab (13). The positive electrode mixture layer (12) is disposed on a surface of the positive electrode current collector (11). The positive electrode tab (13) is electrically connected to the positive electrode current collector (11). The protection layer (410) covers a surface of the positive electrode tab (13). A volume resistivity of the protection layer (410) is within a range of one to 100 times a volume resistivity of the positive electrode mixture layer (12).
